摘要：

Ag atoms and ethylene react at 77 K in inert hydrocarbon matrices in a rotating cryostat to give several paramagnetic mono and polynuclear ethylene complexes. Positively identified by electron paramagnetic spin resonance spectroscopy are Ag[C2H4] and Ag[C2H4]2, and there is tentative evidence for the silver cluster-ethylene complexes Ag3[C2H4] and Ag7[C2H4]x, where x ≥ 1. Magnetic parameters have been assigned to and structures suggested for these zerovalent silver-ethylene complexes. The mononuclear triligand complex, Ag[C2H4]3, is not formed under our experimental conditions.
